I'm working up some little ditties to play for the trick-or treaters, and came upon "Tubular Bells," which was used for the Exorcist. I decided it can all be played with the lower position Harmonics, and started working that up. However, one thing I haven't worked out is that I seem to get a much cleaner sound to the part by picking with just the RH index finger. Trying to alternate RH fingers makes the harmonics speak less evenly. Has anyone else had that experience?
